Well, not sure if you want criticism, since this is my first time giving constructive criticism. I feel like the personality portion is way too small, and falls into the same kinds of issues I see a lot of new characters go into. Why not elaborate upon how he acts? Give more examples, go into pain-staking detail!

His likes are a bit arbitrary, and we can find out from the personality portion he likes to battle. Of course he'd like his friends, can we get some really weird likes, such as enjoying skipping stones across lakes? His dislikes are also a bit arbitrary. Of course he wouldn't like a bully, or a know-it-all. Perhaps we could get an elaboration, or things that are uncommon that he doesn't like? Hell, even being alone / cheaters is something no one would like.

Overall, I think this is a good character with a ton of room for improvement. I believe that the bio you have is much too short for him, personally, as I like to use a biography to map how a character would react and all of that. I'd love to send you a questionnaire for your OC to help cement the quirks that he might have.
